My buell s3 shows no neutral light and fuel pump doesnt turn on and wont start
You have many problems.
1. For the fuel pump
i. Check fuel pump fuse in fuse panel.
ii. Turn on the ignition key to start position without engine cranking.
iii. Listen at the same time for 2 seconds if you can hear the sound of the fuel pump near the fill fuel neck (remove the fuel cap).
iiii. At the fuel pump relay place, a test light back probes the green wire or trigger wire with a test light. It is activated by the PCM (Powertrain Control Module) for 2 seconds (priming the fuel system). /When you start the engine, that same wire will receive a + signal but steady. Then you should find your fuel pump problem. (could be the fuel pump itself not working).
If you need to change the fuel pump.
You have to remove the fuel tank. When the fuel tank is halfway down (before removing the fuel pump) test the + signal at the tank (could be a wires problems)
2. The neutral light problem belongs to the neutral switch system (PRNDL) attach to transmission.
3. Starter Problem
i. Could be rusted positive and negative connections at the battery (Voltage drop in the + battery terminal should not be more than 500mv.
if more remove terminal and clean it. Same thing at the starter motor's end (Same thing with the ground at the Battery to the engine. if OK then the starter motor itself is the defect.
Hope it helps.
